Contrast Media Manufacturing Company

For the purpose of medical imaging, a certain substance is introduced into the human body to change the image contrast of local tissues of the body. This introduced substance is Contrast Media, also known as Contrast Agents. As one of the first contrast media manufacturing companies in China, Beilu Pharma, as one of the most professional contrast media suppliers, contrast media companies, contrast media manufacturers, launched the domestic MRI Contrast Medium Gadopentetate Dimeglumine Injection in 1992, which broke the foreign products monopoly and filled the domestic gap. As a well-known contrast media products company, we could provide various types of MRI contrast and a broad portfolio stems Contrast Media across CT/X-ray and MRI modalities, and own the EU standard manufacturing facilities.

Types of Contrast Media in Bei Lu Pharma
MRI CONTRAST MEDIA
Magnetic Resonance Imaging (MRI)Contrast Media is Gadolinium based contrast agent(GBCA). It is an intravenous injection, mainly used to enhance the image quality of internal organs, blood vessels and tissues during MRI examinations. GBCA contains gadolinium, which is connected to each other through carrier molecules to form a chelating agent. According to the different chemical structures, this contrast medium can be divided into two categories: linear and macrocyclic. The linear structure of the imaging agents is easier to release gadolinium ions, and the macrocyclic structure of the contrast material is more stable and less likely to release gadolinium ions.

CT/X-RAY CONTRAST MEDIA
Iodine-containing Contrast Media is one of the common imaging contrast agents used in radiology diagnosis and interventional therapy. It is also a basic diagnosis drug for cardiovascular imaging under X-ray. Currently, the iodinated Contrast Media used for cardiovascular system CT and digital subtraction angiography are all water-soluble organic iodinated contrast materials.

The osmotic pressure of normal people is about 290-300mOsm/kg.

Taking the viscosity of water as 1, when the temperature is 37℃, the relative viscosity of whole blood is 4-5, and the relative viscosity of plasma is 1.6-2.4.

Three factors of renal injury induced by Contrast Media: Osmotic pressure, Viscosity and the total iodine. Reduced iodine intake is a feasible strategy to avoid kidney damage.
